== 0.6.0 - 11-Apr-2007
* Added support for most BSD flavors, including OS X. The freebsd.c file is
  now just bsd.c.
* The CPU.type method for Solaris has been changed to CPU.cpu_type to avoid
  conflicting with the Object.type method.
* Added a Rakefile. There are now tasks for building, testing and installing,
  among other things. Run 'rake -T' to check your options.
* Many internal directory layout changes - C source files are now under the
  'ext' directory.
* Improved RDoc comments in the C source files.
* Changed CPUError to CPU::Error.

== 0.5.5 - 17-Nov-2006
* Fixed a bug in the Linux version where there could be a key but no
   associated value, causing a String#strip! call to fail.  Now the value is
   simply left at nil.
* Refactored the CPU.processors method on Linux, including the removal of '?'
  from the CPUStruct members for the boolean methods (Ruby doesn't like them).
* Minor tweaks and updates to the documentation, including the README.
* Modified the gemspec so that it sets the platform properly for Linux
  and Windows.

== 0.5.4 - 12-Jul-2006
* Added a gemspec (and a gem on RubyForge).
* The CPU.architecture method on HP-UX now returns nil if it cannot be
  determined instead of "Unknown" for consistency with the other
  platforms.
* Inlined the RDoc and made some minor cosmetic source code changes.

== 0.5.3 - 4-May-2006
* Fixed in a bug in the Solaris version where CPU.load_avg returned bad values
  when compiled in 64 bit mode.  Thanks go to James Hranicky for the spot and
  both James Hranicky and Peter Tribble (via comp.unix.solaris) for patches.
* Made some modifications to the test suite.  You know longer need to know
  which test suite to run.  All platforms now use 'ts_all.rb', which will run
  the appropriate test case behind the scenes.

== 0.5.2 - 24-Jun-2005
* Bug fixed on Linux where empty lines could cause problems.  This affected
  both the install.rb and linux.rb files, though it only seems to have been
  an issue on the 2.6+ kernel.
* Altered the behavior of the CPU.cpu_stats method on Linux.  Now, only the
  numbered cpu entries return associated data, unless the numberless entry
  is the only entry.
* Added a sample program for Linux under the 'examples' directory.

== 0.5.1 - 5-May-2005
* Fixed a potential bug in the FreeBSD version of CPU.model.
* Eliminated some warnings in the FreeBSD version.
* Moved examples directory to the toplevel package directory.
* Renamed and updated the sample scripts.
* Added a sample script for FreeBSD.
* Removed the INSTALL file.  That information is now included in the README.
* Made the CHANGES, README, and .txt files rdoc friendly.
* The dynamic documentation generation for Linux has been altered.  Anything
  relating to rd2 has been removed.  The doc file generated is now
  doc/linux.txt.
* Some $LOAD_PATH setup changes in the unit tests.

== 0.5.0 - 26-Jun-2004
* Now requires Ruby 1.8.0 or later.
* FreeBSD support added.
* Replaced 'CPUException' with 'CPUError'
* The MS Windows version has been completely revamped to use WMI instead of
  the C API.  Some method names have changed and some methods have been
  dropped entirely.  Please see the documentation for details.
* Corresponding documentation updates and test suite changes.
* Sample programs have been moved to doc/examples.
* Installation procedure somewhat revamped.
* No longer autogenerates test file.
* The .html files have been removed.  You can generate the html on your own
  if you like.

== 0.4.0 - 18-Sep-2003
* Added MS Windows support
* Changed some method names.  The "cpu" has been dropped from most method
  names.  See documentation for details.
* The state() and freq() methods (where supported) now assume a default 
  value of zero.
* More unit tests added.
* Fixed minor issue with test.rb for those without TestUnit installed.
* Fixed issue with linux.rb file being auto-installed on non-Linux platforms.
* Minor API change for the load_avg() method on HP-UX.  It now accepts a
  CPU number as an argument.

== 0.3.1 - 16-Jul-2003
* Fixed a bug in the Solaris version that was using up and not
  freeing file descriptors.
* Added html doc for Solaris under doc directory.

  into separate files

== 0.2.2 - 25-Mar-2003
* fpu_type and cpu_type now return nil if not found (Solaris)
* CPUException is now a direct subclass of StandardError
* Modified extconf.rb script
* Minor doc updates
* Added another test to the solaris test suite
* Important note added to INSTALL file

== 0.2.1 - 12-Mar-2003
* Added the cpu_stats() class method for Linux, which contains the
  data from the 'cpu' lines of /proc/stat
* Minor fix for extconf.rb (thanks Michael Granger)
* Some tests added to Linux test suite
* MANIFEST correction
